THE ROLE
We are hiring expert Portuguese (European) transcribers to convert audio recordings of native speakers into precise, conventionally formatted written transcripts. The work powers speech recognition, dialogue, and evaluation systems for major AI labs. Audio ranges from clean studio recordings to natural conversational speech in real-world acoustic conditions.
You will be working at the level of expert linguistic judgment. This is not data entry. Decisions about orthography, code-switching, speaker attribution, disfluencies, and non-speech events shape the quality of every model trained on your output.
DIALECT AND SCOPE
Portuguese in either its European or Brazilian standard, depending on the project. The two varieties differ significantly in phonology, vocabulary, and certain grammatical features. The project lead will specify the target variety and regional focus before onboarding.
Primary speaker regions: Variety set per project (European or Brazilian).

Experience with verbatim versus clean-verbatim transcription conventions
HOW WE WORK WITH YOU
Paid pilot task before full onboarding so both sides can calibrate
Per-task or per-minute compensation, with rates tied to audio complexity and turnaround
